I stayed at Koj & Pear's condominium for almost 1 month. It's a small building set back in a quiet alley. Their cute cart car would take you and pick you up from BTS Phrom Phong or you might enjoy a short serene walk in 5 minutes. Staff is friendly and service oriented. The unit itself is spotless clean and cozy, very well- appointed, charming deco/furnishings, kitchenette, and a great bed. Fast Wifi and Apple TV are bonuses!
Check-in/out was hassle-free. The host Koj is probably one of the most friendly guys that I have ever met. He will be pleased to provide you everything you need and always makes himself available for you. For example, he would bring the bottles of drinking water throughout the stay, change the bedsheets every 2 weeks, etc. He makes sure that you feel at home and that makes your stay even more pleasurable. There is supermarket available, and there are shops and restaurants within the vicinity. We enjoyed the authentic Thai foods at Klang Soi Thai Restaurant (Thonglo), and every single dish is a real Thai homey style cooking. I would most definitely recommend staying in their home to anyone traveling to Bangkok.
